Another possibility would be the conrad-johnson CA200. I own one so therefore I'm prejudiced but it did replace some more costly separates (also conrad-johnson) and I've been very pleased. There are a few available now on Audiogon within your budget. I'm not familiar with your speakers but I do have an Oppo 105D which I use almost exclusively with either external hard drives or solid state drives. so that's a common point of reference. I find the CA200 to be an excellent match with the rest of my system and it has simplified my life.
Just a thought.
